“…Photocatalysis typically entails a semiconductor being exposed to light containing photon energy greater than the band gap energy of the material. As a result, photogenerated holes and photogenerated electrons are formed, leading to the generation of •OH, •O 2 − , and 1 O 2 when dissolved oxygen, protons (H + ), or water (H 2 O) are present (Equations (1)−( 5) in Table 1) [10]. The Fenton system is a traditional advanced oxidation process mode, and the classic Fenton reaction is performed by the •OH produced by the reaction of Fe 2+ to H 2 O 2 (Equation ( 6)).…”

Recently, biochar has emerged as a promising option for environmentally friendly remediation due to its cost-effectiveness, extensive surface area, porosity, and exceptional electrical conductivity. Biochar-based advanced oxidation procedures (BC-AOPs) have gained popularity as an effective approach to breaking down organic pollutants in aqueous environments. It is commonly recognized that the main reactive locations within BC-AOPs consist of functional groups found on biochar, which encompass oxygen-containing groups (OCGs), imperfections, and persistent free radicals (PFRs). Additionally, the existence of metallic components supported on biochar and foreign atoms doped into it profoundly impacts the catalytic mechanism. These components not only modify the fundamental qualities of biochar but also serve as reactive sites. Consequently, this paper offers a comprehensive review of the raw materials, preparation techniques, modification approaches, and composite catalyst preparation within the biochar catalytic system. Special attention is given to explaining the modifications in biochar properties and their impacts on catalytic activity. This paper highlights degradation mechanisms, specifically pathways that include radical and non-radical processes. Additionally, it thoroughly examines the importance of active sites as catalysts and the basic catalytic mechanism of BC-AOPs. Finally, the potential and future directions of environmental remediation using biochar catalysts and advanced oxidation processes (AOPs) are discussed. Moreover, suggestions for future advancements in BC-AOPs are provided to facilitate further development.
